Product details
Overview
VNL5160S5-E from STMicroelectronics is an automotive-qualified, monolithic low-side driver IC built with VIPower® technology, designed to switch resistive or inductive loads (e.g., R10W/2×R5W signal lamps) with one side connected to battery voltage. It delivers 3.5 A DC drain current, features 41 V overvoltage clamp, thermal shutdown with automatic restart, and integrated open-drain status output for diagnostics.
For engineers reviewing the VNL5160S5-E datasheet, VNL5160S5-E pinout, VNL5160S5-E application, or VNL5160S5-E equivalent, this device supports robust load control in harsh automotive environments where overtemperature, short-circuit, and open-load detection must be handled autonomously without external circuitry.
Technical Context
The VNL5160S5-E integrates a PowerMOS output stage with active current limitation (IlimH = 3.5–7.5 A), thermal shutdown at 150–200 °C, and fast demagnetization for inductive loads. Its logic-compatible input accepts 0.9 V (low) / 2.1 V (high) thresholds with 0.13 V hysteresis, enabling direct MCU I/O interfacing.
It includes dedicated diagnostic functions: open-load detection (VOL threshold 0.6–1.7 V), status pin with 0.5 V low-level output at 1 mA, and ESD protection up to 5 kV on DRAIN. The SO-8 package provides 103.1 °C/W junction-to-ambient thermal resistance on standard FR4 PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Drain Current (ID) | 3.5 A DC - supports automotive lamp loads up to R10W or dual R5W configurations without external heatsinking under typical ambient conditions. |
| RDS(on) | 160 mΩ @ 5 V, 1 A, 25 °C - ensures <170 mW conduction loss at 1 A, minimizing self-heating during sustained operation. |
| VCLAMP | 41 V (typ.) - clamps inductive kickback to protect downstream electronics during turn-off of 12 V automotive loads. |
| Thermal Shutdown Threshold | 150 °C (min.) - triggers automatic power cycling to prevent permanent damage during overload or poor PCB thermal design. |
| Status Pin Output | Open-drain, 0.5 V max @ 1 mA - enables wired-OR diagnostics and direct connection to 3.3 V/5 V MCU GPIO with pull-up resistor. |
| Input Hysteresis | 0.13 V - rejects noise on control lines in electrically noisy vehicle cabins, preventing false turn-on/off transitions. |
| ESD Protection (DRAIN) | 5000 V (HBM) - exceeds ISO 10605 requirements for automotive component robustness against electrostatic discharge. |
Pinout & Package
Package: SO-8 (ECOPACK®, RoHS-compliant, 5.8 × 4.9 mm footprint). Thermal performance optimized for 2 cm² copper pour on standard FR4 PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| INPUT | CMOS-compatible logic input | Accepts 0.9–2.1 V logic levels; internal hysteresis prevents chatter; no external pull-up required. |
| DRAIN | PowerMOS drain terminal | Connects to load (e.g., lamp filament); handles up to 41 V clamp voltage during inductive flyback. |
| SOURCE | PowerMOS source & ground reference | Common return path for load current and internal control circuitry; must connect to system ground plane. |
| SUPPLY | 5 V logic supply input | Separate 4.5–5.5 V rail powers internal logic and diagnostics; decoupling capacitor required near pin. |
| STATUS | Open-drain diagnostic output | Asserts low during overtemperature, open-load, or undervoltage; high-impedance otherwise; requires external pull-up. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 0 (−40 °C to +150 °C junction), certified for safety-critical lighting systems. |
| Integrated open-load detection | Validates load continuity before and during operation; reports fault via STATUS pin within 45–1100 µs of open condition. |
| Active power limitation | Maintains safe dissipation during prolonged overload by dynamically reducing current to limit power below thermal trip point. |
| Very low standby current | 10–25 µA supply current in off-state - minimizes battery drain in always-on vehicle modules (e.g., daytime running lights). |
| Low electromagnetic susceptibility | Immune to conducted/radiated noise per ISO 11452-4; eliminates need for additional filtering in compact lamp control units. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS27082L (Texas Instruments) | Lower RDS(on) (80 mΩ), but only 2.5 A rated; no integrated open-load detection; requires external status monitoring. | Best suited for space-constrained, lower-current applications where diagnostics are handled externally. | Select when board area is critical and load current ≤2.5 A; verify external fault handling meets functional safety goals. |
| BTS7008-1EPA (Infineon) | Higher current rating (6 A), integrated current sense (0.5 V/A), but larger PG-DSO-8 package and higher quiescent current (100 µA). | Preferred for systems requiring analog current feedback or higher drive capability beyond 3.5 A. | Choose when real-time current monitoring or >3.5 A peak load support is mandatory; accept larger footprint and higher idle power. |
Compared with TPS27082L and BTS7008-1EPA, the VNL5160S5-E uniquely balances automotive-grade protection, integrated diagnostics, and SO-8 form factor for mid-power lamp control-offering optimal trade-offs in cost, reliability, and design simplicity for R10W-class applications.

FAQ
What is the maximum continuous load current the VNL5160S5-E can drive in free-air conditions?
The VNL5160S5-E supports 3.5 A DC drain current continuously when mounted on a standard SO-8 PCB layout with ≥2 cm² copper pour and ambient temperature ≤85 °C. At higher temperatures or reduced copper area, current must be derated per the 103.1 °C/W Rthj-amb value and thermal shutdown threshold of 150 °C.
Does the STATUS pin require an external pull-up resistor, and what voltage level is compatible?
Yes-the STATUS pin is open-drain and requires an external pull-up resistor to a logic-compatible voltage (3.3 V or 5 V). It sinks up to 1 mA with ≤0.5 V drop, ensuring clean low-level assertion for MCU GPIO detection. Pull-up values between 4.7 kΩ and 10 kΩ are recommended for noise immunity and speed.
How does the VNL5160S5-E handle inductive load demagnetization, and is an external freewheeling diode needed?
The device integrates active clamp circuitry that limits VDS to 41 V during turn-off, safely dissipating demagnetization energy internally. No external freewheeling diode is required-verified for 8.5 mH inductive loads with 13.5 V supply and 37 mJ single-pulse avalanche energy rating.
Can the VNL5160S5-E be used with a 3.3 V microcontroller I/O without level-shifting?
No-its INPUT pin requires VIH ≥2.1 V and VIL ≤0.9 V, but its SUPPLY pin mandates 4.5–5.5 V. A 3.3 V MCU can drive INPUT directly (since 3.3 V > 2.1 V), but the IC itself must be powered from a separate 5 V rail; logic and supply domains are isolated per datasheet Figure 8.
